Application led August 31, 1921. Serial" No. 497,131.

Tp all whom t may concern:

Be it known that I, WILLARD A. HANCE, a citizen of the Unitedl States, residing at Freeport, in the county of Stephenson and State ofIllino is, have invented a certain n ew and useful Improvement in Stovepipe Dampers, of which the following is a specification.

coiled spring handle 24 of the type shown 'in Figure 1 which replaces the unsatisfactory cylindrical wooden handle of said prior patent. In assembling the device a conical coiled spring 26 corresponding to spring 18 This invention relates to stove pipe dampers of the general type shown in Patent 541,- 162, to A. Held, dated June 18, 189,5. The object of 'the invention is to improve the device of said patent by providing a novel form of spindle and handle therefor which is both cheaper to make and more efficient and satisfactory in use. v

Referring to the drawing in which'like numerals represent the same'parts throughout the several views,

Figure 1 shows a damper equipped with the device of this invention.

Figure 2 is a perspective View of the spin-` dle and handle device attached thereto removed from all other parts.

Figure Bshows the device'equipped with a wooden handle. i

As in said prior patent, the numeral 1. in-l dicates the damper blade which is formed with theusual central opening from which radiate oppositely disposed spindle bearings 2 of semi-circular form so that the round spindle 7 can turn freely in them when required. 3 indicates the vouter bearing ofthe blade of sufiicientrsize to allow the spindle to pass through it, as fully set forth in said prior patent.

of the prior patent is inserted about the spindle 7 adjacent to the point 16 heretofore sol indicated, the same taking bearing at one patent, the pressure of the right hand end of f' vthe springs 26 on the members 18 and 20 tends to force them together and onto the spring handle 24, thus more securely holding it in place.

Figure 3 of the drawing merely shows the .device of Figure 1 with the wooden handle 28 substituted for the spring handle 24.

Having thus described my invention, what ters Patent,` is:

1. In a device of the class described, a damper plate, a pivoting spindleextending across the damper plate, having one end extending beyond it, the last mentioned end of the spindle being divided into oppositely Detachable spindle 7 is sharp pointed to adapt its pointed end 8 to readily penetrate a stove pipe not shown. The spindle 7 is provided intermediate of its length with. a pair of locking lugs 9 corresponding to those of the prior patent adapting it to interlockl with one of the bearings 2 as shown in Figure 1. It is also provided with another pair of lugs 14 adapted to interlock with the washer or colla-r 15, resting uponthe bearing 3. The right hand or operating end of the spindle beyond lugs 14 is constructed disposed reversely curbed members terminating in aligned ends pointed toward each other, a handle member between the free ends of said reversely curved members entered at its ends by said ends of the curved 'members and a coiled spring embracing the spindle bearing at one end against said re. versely curved parts of the spindle and bearing at the other end on the damper plate, for the purposes set forth.

2. In -a device of the class described, a`

damper plate, a pivoting spindle extending across the damper plate, having one end exquite differently from Vthe device of saidprior patent, in that it is divided at the point 16 into two reversely curved branches 18 and 20, having aligned terminal ends 22 pointed toward each other lwhich enter the tending beyond it, the last-mentioned end of the spindle being divided into oppositely disposed reversely curved members, a coiled wire handle member between the free ends of said reversely curved members entered at its ends by sald curved members and a coiled 80 I claim as new and desire to secure by yLet- 10 aligned ends pointed toward each other between which a spindle handle proper' may be inserted.

In witness whereof, I have hereunto subscribed my name in the presence of two witl HGSSGS.

WILLARD A. HANCE.
